Continuity and Change in Women's Characteristics over Four Decades
Fifty-three mothers of participants in the Guidance Study of the Institute of Human Development at the University of California, Berkeley, were rated on 21 cognitive and personality-social characteristics at approximately 30 years of age and again at age 70. As judged by the interage correlations, all 5 of the cognitive variables and 10 of the 16 personality variables, proved to be relatively stable over the 40-year period. Ratings of intelligence, mental alertness, speed of mental processes, use of language, and accuracy in thinking were relatively consistent and the following personality-social characteristics also showed continuity over the 40-year interval: talkativeness, cheerfulness, frankness in discussion, tendency to criticize, excitability, energy level and self-esteem. Ratings of self-assurance, attitude toward child and satisfaction with life showed little stability over this long interval. A new factor analytic method was used to extract 3 factors common to both ages, together with 2 factors specific to age 30 and 3 factors specific to age 70.
